441 NO.1 Stainless Steel Flat Bar，441 is made of stainless steel. Resistant to air, steam, water and other weak corrosion media or with stainless steel called stainless steel; And the chemical corrosion medium (acid, alkali, salt and other chemical erosion) corrosion of steel called acid resistant steel. Due to the difference in the chemical composition of the two and their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical media corrosion, and acid resistant steel is generally rust free.

439 NO.1 Stainless Steel Flat Bar 439 steel is to reduce the content of C on the basis of ordinary ferrite material (430), while adding Ti and other stabilizing elements, so that the resistance to intergranular corrosion, formability and weldability of the steel are improved. Compared with 304 steel, although the elongation is lower (about 30%), but the strength, corrosion resistance is equivalent, and corrosion resistance is better than 200 series materials.
